Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus and method for identifying faults in a digital logic circuit system combines the output of a feedback signature generator and synchronous transition counter to provide a unique signature which is sensitive both to bit pattern timing and bit pattern sequence.  A plurality of output signals via signal lines of the circuit system which are produced in response to a preselected input signal pattern of a test signal generator is processed synchronously under control of a sequence controller through a feedback signature generator, such as a serial cyclic redundancy check network, and a synchronous bit transition counting network.   A preselected portion of the outpout of the bit transition counting network is combined via a signal line with a preselected portion of the bits of the feedback signature generator to obtain a pseudo-random characteristic output bit pattern, or signature, which is unique to the circuit system under test.  The fault detecting capability approaches one hundred percent with an embedded indication of the input test pattern duration as verification.

Abstract: ABSTRACT OF THE DISCLOSURE         A non-return valve unit for a bottle having a mec-hanism for preventing dripping and for giving a controlled discharge of liquid from the bottle, suitable for use with any type of bottleneck by insertion in the said neck and especially for bottles adapted to receive "pilfer-proof" caps.  The valve unit consists of only three elements made up generally of a cylindrical slightly frusto-conical body having a brim for preventing dripping and having a septum in its interior where the seat of a generally circular valve is positioned.  Radial septa which support an annular guide for the stem of a check or retention valve, form a component part of this septum.  An upper chamber in the body houses a pouring device of a frusto-conical shape.  The pouring device has a cylindrical wall internally supported by radial septa which ends in a frusto-conical surface; and provides together with the inner cylindrical surface of the pourer a circular area of discharge.  The pouring device also provides guide ridges for guiding the movement of the upper stem of the retention valve which, on moving upward rests against the lower edge of the said inner cylindrical wall.  The shape of the base of retention valve being the same as that of the inner frusto-conical sur-face to which the assembly is connected, providing, when the valve rises for the discharge of the liquid by tilting the bottle with the inner wall of the pourer, a discharge circular space allowing a controlled discharge free of turbulence.

Abstract: 1               PHN.9233C.      ABSTRACT:           In electric lamps a type of glass is used for the envelope which, in many cases, has a coefficient of expansion which differs considerably from that of the current supply conductors.  Therefore, special measures have to be taken to seal the lamp envelope in a vacuum-tight manner around the current supply conductors.  The invention provides a simple, vacuum-tight seal of a lamp envelope, which seal consists of a metal plug which is sealed both to the glass of the lamp envelope and to the current supply wires.  The metal plug of 100 parts by weight of a first metal (tin and/or lead) 0.05-1 parts by weight of a second metal (titanium, zirconium, haf-nium, niobium, tantalum, and vanadium) has a strong adhering power and a large ductility.

Abstract: Title METHOD AND APPARATUS FOR CONTROLLING COMFORT CONDITIONS       INCLUDING SETBACK     Inventors James F. Saunders Robert E. Krocker Abstract Method and apparatus are disclosed for control-ling and selectively setting back the comfort condition, such as temperature, within a conditioned zone utilizing a system which includes both preferred and back-up condi-tioning means, the former exhibiting more favorable energy consumption characteristics than the latter.  The system is operable in both a normal mode, and in an economy mode during which the comfort condition is permitted to degrade toward an economy level during a setback period of prede-termined duration.  Selective operation of the preferred and back-up conditioning means is effected in order to minimize energy consumption during both modes and especially during the time that the comfort condition is restored to the normal level from the economy level.  In a preferred embodiment, the preferred conditioning means comprise an electrically operated heat pump of the vapor compression type and the back-up conditioning means comprise electrical resistance-type heating means.  A second aspect of the present invention involves the provision of a system which includes a refrigeration system for cooling a conditioned zone in conjunction with economizer means for supplying cool ambient air to the conditioned zone during those times when it is available and wherein operation thereof is effected in both normal and economy cooling modes so as to minimize the overall energy consumption of the system .

Abstract: SYNCHRONIZATION SIGNAL DETECTING CIRCUIT                   ABSTRACT OF THE DISCLOSURE          A synchronizing signal detecting circuit for synchro-nizing digital data receiving equipment is disclosed.  Digital signals consisting of data and synchronizing signals obtained by repeating a  predetermined pulse pattern many times are fed to a shift register in succession in synchronism with clock pulses.  A gate circuit connected to the shift register detects the synchronization pulse pattern.  A detector circuit detects a duration period of a coincidence signal which is the output of the gate circuit, and outputs a synchronous detection signal when the duration period of the coincidence signal exceeds the predetermined value.  This synchronizing signal detecting circuit can detect synchronizing signals even when data errors are produced to some extent.

Granted: 1982-09-14
Abstract: MARINE SEWAGE DISPOSAL Abstract An activated sludge marine sewage disposal apparatus includes an aeration chamber immediately adjacent to a flooded settling tank, rising above a disinfectant chamber and a holding chamber disposed around the lower part of the tank.  Flow from the aeration chamber to the settling tank is through a port in the common wall between the aeration chamber and settling tank, and up inside a pond separated from the rest of the tank by a downwardly flaring baffle or skirt depending from the top of the tank.  A single skimmer at the center of the area at the top of the pond picks up floating solids and returns them to the top of the aeration chamber.  A vent disposed directly over the skimmer continuously draws off air and gas to the aeration chamber.  A sludge return line picks up heavy solids from the bottom of the tank and returns them to the top of the aeration chamber through a riser located in the aeration chamber  Liquid in the settling tank flows out through a submerged perforated pipe into a standpipe in the aeration chamber, which is located centrally in the aeration chamber and overflows through an inverted-U tube, vented to the aeration chamber, the tube connecting to a downcomer sending the liquid back through the common wall to the disinfectant compartment. When sufficient volume of fluid accumulates in the disinfectant compartment, it overflows into a holding tank, from which it emerges via a port.
